Artifacting on asciinema.org - looks good in CLI player

See the 30 second mark at drush entity:create - asciinema. I edit the line with ‘field_number_of_servings’ but the line above starts to obscure it - field_media_image. This artifacting does not happen when I play in my CLI so I think the file is OK, and its a player bug. Note that I’m editing in nano so interactive commands.
